They were 1 mile away from each other.
4-3=1 mile
ln(20) + ln(5) = 2 ln(<em>x</em>)
ln(20×5) = ln(<em>x</em> ²)
ln(100) = ln(<em>x</em> ²)
100 = <em>x</em> ²
<em>x</em> = 10
<em>Answer:</em>
<em>The value of the number should be 1 (or less I think)</em>
<em>Step-by-step explanation:</em>
<em>At most means the highest value of the sum should be 27.</em>
<em>10x + 17 = 27</em>
<em>10x = 27 - 17</em>
<em>10x = 10</em>
<em>x = 10/10</em>
<em>x = 1</em>
<em>∴</em><em>The value of the number should be 1</em>
